2. Safety Devices
※
We adapt 5 safety devices for users to use this wash machine safely.
1) Balancing device (ASSY-Main PCB)
→
When the laundry is out of balance, to prevent the noises and vibrations, the unbalance
detecting sensor helps the laundry laid even and continue the dehydating process.
2) Anti-over water supply device
→
Because water supply value is broken, once water is supplied to the 2/3 level of the door, the
water supplied is drained automatically, Over -flow error is displayed on the panel
3) Temperature-regulating device(thermistor)
→
To prevent over-heating over the temperature setted up, THERMISTOR senses the temperature of
the machine continuously and helps the wash machine to work at the temperature given by users.
4 Overheating- controlling system
→
Under the circumstances of THERMISTOR inferiority or abnormal condition, if wash-heater is
overheated, automatically, assy -thermal fuse cuts off the power supply to protect the machine to
keep it safe.
5) Delicate clothing safeguard function(ASSY-Main PCB)
→
To protect the clothings which is weak to high temperature, the wash machine senses the
temperature inside the washing tub. if the temperature rises over 50℃wool washing course and
Delicate washing course display abnormal water temperature on the panel , after draining the
water.

1) Auto power S/W off function
●
After power on, the auto power S/W off function automatically switches power off for you if you do not press
selection button for 10 minutes
●
After selecting the function, the auto power S/W off function automatically switches power off for you if you do
not press start/pause button for 10 minutes
●
After finishing the last function, the auto power S/W off function automatically switches
power off for you if you do not re-select the course button or manual button
2) Door open function
●
If door is open during the operating, all operating is halted, and door error message will be displayed and error
molody wil coming out.
●
Door open error can be cleared by colosing the door. the operating keeps going on
3) No spin function
●
If no spin function selected, the operating is finished after last rinse

4) Power-out compensation function
●
If power is out on selected process, the process before power out is stored to EEPROM, once power is back
the process before power out continues.
●
When power is back, washing process starts from the process at the point of the power out, rinse/drain process
starts from the initial process.

5) Water heater Error function
①
This function starts working, when the heater works abnormally.
(this function begins sensing the heater 1 minutes later, after the heater operating)
②
The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 2 minutes (Y=A2-A1)
- For 10 minutes, the variance of temperature(Y) is less than 2℃"The display shows 'E5' "
message is displayed on the panel.
③
The value of the initial thermistor(A1) is compared with that of the thermistor(A2) in 2 minutes (Y=A2-A1)
- For 2 minute the variance of temperature increases more than 7℃"The display shows 'E5' "
message is displayed on the panel.
④
At this time heater, Error "course led 8ea on 30℃/60℃led on" is displayed and all working process off
⑤
The heater operating continues during heating hours, if washing hour is left over, the residual washing process
keeps going without heating.

6) Fuzzy washing function ( weight-sensing)
☞
After finishing initial water supply, when the fall of the water level needs supplementary water supply,
Sensing function perceives the weght with the supplementary water supply numbers and starts to work.
Under the course of Cotton, if the supplementary water supply numbers become 3 - 4 times the
function is going at default condition ( high water level ), if 1-2 below that is going at middle level, if 0 below
low water level, heating hours and rinse hours depend on the above data.

Middle Default-12 min 23.30KHZ

After sensing weight, above hours is decreased from above default hours
7) Bubble -detecting function
At the each condition of washing&dehydrating , rinse&dehydrating , hydrating, bubble -detecting function works,
this function works 5times normally, if the function detects bubbles at 6 times , the bubble-detecting function
stops and go on to the next process.

8) Unbalance detecting & laundry balance positioning system
①
Just before the hydrating process and just after reversal rotation for balancing laundry position, this function is
carried out
②
The initial 6 sec is the period of reversal rotation for balancing laundry position , Drum rotates 50rpm for
initial 6 sec
③
Next 10 sec, the rotation increases the speed from 50 rpm to 90 rpm slowly
④
During the next 18 sec, drum rotates at the speed of 90 rpm, the sensor decides the degree of laundry
unbalance with TACHO data which is attached to motor
⑤
If the degree of unbalanced laundry is over 6 times to default value, laundry balancing system carryies out
feed back process 6 times

7. General Error Function
When an error occurs, this function starts to keep generating error melody sounds and displays error indicators as
l
shown in the followings per corresponding error by blinking in 0.5sec interval until the error status is completely cleared out.
In this case, all the driving devices are turned off until the error is cleared out.
1. WATER SUPPLY ERROR
- Display shows ‘ E1’ .
- Water Supply Error occurs when water level frequency does not show changes more than 100Hz or water is not supplied
up to the water level presetting for 20 min or more at the time of initial water supply.
- The error status can be cleared by turning POWER S/W OFF and resuming the POWER ON initial status.
2. WATER DRAIN ERROR
- Display shows ‘ E2’ .
- In case the water level frequency is 25.5KHz or less in the initial phase of UNB-detecting cycle.
- Water Drain error can be cleared by turning POWER S/W OFF and resuming the POWER ON initial status.
3. OVER-FLOW ERROR
- Display shows ‘ E3’ .
- Over-Flow error occurs when the water level is in abnormal operation. It can be cleared by turning POWER S/W OFF.
Water is drained prior to POWER S/W OFF and it is forced to be drained for 2 min if a frequency of more than 25.24
KHz is detected.
4. DOOR OPEN ERROR
- Display shows‘door
- Door Open error can be cleared by closing the door.
5. UNBALANCE ERROR
- Display shows ‘ E4’ .
- Laundry load is unbalanced; loosen any tangled laundry.
- If only one item of clothing needs washing, such as a bathrobe or jeans, the final spin result might be unsatisfactory and an
“ E4” error message will be shown in the display window.
- Unbalance error is cleared by POWER S/W OFF and by resuming the POWER ON initial status.
6.WATERHEATERERROR
- Display shows ‘ E5,E6’ .
- In case the water temperature rises by 7° C or more in 1 min. or by 2°C less in 10 min after heating is started.
- It can be cleared by turning POWER S/W OFF.
7. ASS’ Y PRESSURE S/W ERROR
* Generated Frequency Signal of WATER LEVEL(W/L) S/W (KHz)
’
Level Low Level High Level
Abnormal W/L Frequency 30.00 KHz 15.00 KHz
- If the same signal as the above table is detected for more than 5 seconds, it is a PRESSURE S/W Error.
- When the error occurs, water drain pump will operate for 3 min. and then turn off the water drain pump.
Then the display shows ‘ E7’ indicating a pressure s/w error indicator.
8. ABNORMAL WATER TEMPERATURE ERROR
Course Water Temp
Delicate 50°C or more
Wool 50°C or more
- In case the water temperature is 50° C or more in Delicate and Wool course.
- At the time of initial water supply, if the water temperature is not appropriate, water starts to be drained
and it is forced to be drained for 2 min when the abnormal frequency of 25.24 KHz is detected.
- Display shows ‘ E8’ .
- This error can be cleared by POWER S/W OFF.
9. WATER LEAKAGE ERROR (E9)
- Water Leakage error occures when water is drained naturally after washing program starts.

10. Tacho Error
- This error occurs in case motor thaco is out of order or tacho siganals inputted are fewer than 2
- "EA" displayed
- This error can be cleared by power s/w off
11. Motor Triac short Error
- This error occurs in case over 300 per 1 sec tacho signals are inputted power S/w should be off.
-"Eb"diplayed.
- This error can be cleared by power s/w off
12. Thermistor error
- This error occurs, when Thermistor circuit is abnormal or the detected electrical volt is 0.2v below or 4.5v over
- "Ec" displayed
- This error can be cleared by power s/w off
